1 x N optical switch

Abstract

An optical switch is provided which is capable of driving control by the same FPGA and the same driving circuit configuration, and hence is capable of driving at a high speed and a low consumption power. The optical switch of the present disclosure is a 1×N optical switch having a structure in which with respect to an optical switch, a driving circuit of the optical switch is integrated in the vicinity of a control electrode of the optical switch. The optical switch includes a plurality of 2×2 optical switches and N optical gates. Different bias voltages (Vb) are set between the optical switches and the optical gates, and a driver for the 2×2 optical switch of the driving circuit and a driver for the optical gate are of the same circuit form.
